T o all whom it may concern: Be it known that I, Gnonon R. TAYLOR, acitizen ,of the United States, residing in the city andA county of SanFrancisco and State/of California, have invented new aiid usefulimprovements in rlelephone-Mouthpices, of which the following is aspecification.

'My invention relates to improvements in the mouth-pieces of telephonesinto which spoken words are delivered.

1t consists of a mouthpiece mounted independently, and at a distancefrom the diaphragm-containing portion of the appay .ratus, with supportswhereby an open unobstructed space is provided between the mouth-pieceand the operative parts.

.My invention also comprises details of construction which will be morefully explained by reference to the accompanying drawings, in which-Figure 1 is an exterior View showing the application of my device. Fig.2 is a sectional View in line with the axis. Fig. 3 is a section showingthe transmitter openings.

It is the object of my invention to provide, first, a superior sanitarymouth-piece for telephones; second, to insure a more direct delivery ofspeech to the transmitting mechanism, and to avoidthe confusion oftencaused by the sound-waves striking the sides ot' a closed mouthpiecebefore entering the transmitter.

A is the ter mechanism, and may be of the usual er any suitableconstruction.

2 is the perforated disk through which the sound waves enter thetransmitter.

3 is the mouth-piece, the outer portion of which is divergent as shown,and the inner portion is here shown as being cylindrical for a shortdistance, but it will be manifest that the form of the mouthpiece maybe` varied to suit `the conditions or taste.

This mouth-piece is supported at.a..consid' erable distance from thepart 2 b means of arms or standards l4f, the inner en s ot which may befixed to a ring 2 surrounding the.

part .2, or otherwise have a firm attachment ortion containing thetransmit' to some portion of the transmitter. These `arms or standardsextend outward, and the outer ends are fixed to the mouth-piece 3 asshown. Any suitable or desired :numb r ot' these arms or connections maybe empldyed. 'I have here shown two which form a sufli* cient su port,with a minimum of interfering sur aces between the mouth-piece and Y thetransmitting portion of the device. The mouth-piece being open, speechor other sounds delivered into the mouth-piece, meet with no surfaces todefiect or change their character, and enter dii'ectly'into thetransmitting mechanism through the perforated plate 2, thus overcoming avery considerable difficulty which occurs when the. Jerson who isspeaking does not talk directly into the axis of the mouth-piece, andunder such conditions, the sides of a closed mouth-piece. will defiectthe vocal vibrations to such an extent that they are almost or quiteunintelligible at the receiving end. This is overcome in my device,since there are no surfaces extending from the outer to the innerportion of the mouth-piece.

The most important part ot' the invention l between the mouth-piece andthe transmit ter, and thc whole apparatus is very easily maintained in aclean and wholesome condition withou't other attachments.

Having thus described my invention, whatl claim and desire to secure byLetters Patent is 1 1. The combination in a telephone transmitter, of amouth-piece having its inner end supported at a distance from andsubstantially in axial line with the transmitter to thereby provide anintervening, substantially unobstructed, transverse space between theback of the mouth-piece and the front of the transmitter.

2. The combination with a transmitting mechanism of a telephone, of amouthpiece, supports or standards extending from the mouth-piece to thetransmitter, and foaming open .unobstructed spaces between` saidsupports.

'3. The combination with a transmitting mechanism of a telephone, of 'anndepend- In testimony whereof I have herent set ently supportedmouth-piece substantially infa'xal line with the transmitter, stand-Witnesses. lards or'supports having the outer ends ut- GEORGE R.
